Little was said about Touch ID in the WWDC keynote except that the API would be opened to third-party developers for use in iOS 8. Craig Federighi did show a nice pie chart claiming that since the introduction of Touch ID on the iPhone 5s, 83% of users now use passcodes, up from the 49% that used their iPhone’s security previously. Just days after this announcement, PayPal is reportedly dipping their toes into the Touch ID API with hopes of incorporating fingerprint recognition into their iOS app’s authentication system. This isn’t really surprising as it has already done this on Android with the Samsung Galaxy S5. Hopefully the process will be more hacker-proof on iOS.

PayPal may just be the first of several companies including other mobile payment services, banks, and even large retail chains, to take advantage of access to Apple’s fingerprint scanner. Getting users familiar with using Touch ID for purchases may be just the first step in Apple’s own long rumored plans to get into the mobile payments game, using it in tandem with their Passbook software. Apple is expected to start building Touch ID sensors into all of its mobile hardware soon. Here’s hoping the technology becomes more reliable than many users’ past experiences or people may get frustrated with the process and just not use it.
